New Release: Tor Browser 10.0a6

Tor Browser 10.0a6 is now available from the Tor Browser Alpha download page and also from our distribution directory.

Note: This is an alpha release, an experimental version for users who want to help us test new features. For everyone else, we recommend downloading the latest stable release instead.

We are happy to announce the second alpha for desktop users based on Firefox 78 ESR. The Android version is under active development and will be available in the coming weeks.

We released the first alpha version based on ESR 78 one week ago.

Tor Browser 10.0a6 ships with Firefox 78.2.0esr, and updates NoScript to 11.0.39. Please report bugs with steps to reproduce, either here or on Gitlab, or essentially with any other means that would reach us. We are in particular interested in potential proxy bypasses which our proxy audit missed.

Also, this release features important security updates to Firefox.

Note: Android Tor Browser is still based on Firefox 68esr. As a result, Android and desktop packages were built separately, based on tag tbb-10.0a6-build1 and tbb-10.0a6-build2 respectively. The resulting sha256sums-unsigned-build.txt files were merged and signed before publishing.

Note: We encountered updater issues for all alpha users that have been auto-updating the alpha series for months. We changed the accepted MAR channel ID to torbrowser-torproject-alpha as we are on an alpha channel. The assumption was that enough time passed since we changed it last time to torbrowser-torproject-release,torbrowser-torproject-alpha but it turns out that change did not get applied. Workaround: change the torbrowser-torproject-release in your update-settings.ini (in the Browser's code directory, which depends on you operating system) file to torbrowser-torproject-alpha and the update should get applied successfully. Alternatively, downloading a fresh alpha copy of Tor Browser works as well. Sorry for the inconvenience.

I just saw devtools.onboarding.telemetry.logged in my 9.5.4 and 10.0a6 with a value of true. Is this a bug?

I have a buglet to report. If I use Tor Browser to navigate the file system (e.g., if I want to view files in /tmp), the page does not load properly. Instead, it seems to keep stopping and starting to load the page but it never actually shows the directory listing. I ran into this on 10.0a6 on linux64.

Tor Browser goes crazy trying to load my plain old HTML file which I use as a home page. And another plain text file I tried. Here's what happens.

Activity Monitor on Mac shows an impressive 109% CPU consumption rate for the "Tor BrowserCP file:// Content" process with Tor Browser process around 80-90%.

The Tor Browser window shows the X and Reload icon changing very fast. The tab label text is likewise cycling back and forth as fast as it can.

It seems to have issues with loading local text files. Pages retrieved via http(s) are fine.

Also, has the rqef5a5mebgq46y5.onion address gone away? It doesn't seem to load any more. I preferred that to the less secure domain name option. :-)

When I use a bridge, the circuit diagram in the "site information" menu on the URL bar displays the bridge's IP address. Isn't it dangerous to display a bridge's IP address in the main interface that is frequently visible to shoulder-surfers? You make it necessary to reveal it to reach the New Circuit button. Wouldn't it be safer to display the bridge's hashed fingerprint or a link to open the Tor preferences tab to view details?

Sorry, I don't know which post to write this in.

Dear web team, update the name "OS X" to "macOS" on the download page.

Discussion for new alpha
https://blog.torproject.org/new-release-tor-browser-100a7
is closed, i try it here:

Why extensions-/storage-directory will be mixed again?
https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/320
Switch back extensions.webextensions.ExtensionStorageIDB.enabled = true

Super idea? No, it was a bad idea and is a bad idea.
For programmers, ...i don't know. For me, for the user mixing is a useless, a not so good thing.
Separate the directory for extensions and storage, clearly laid out, is really better and there is no need to mess up this? I really see no need for this. No offense.
